To all whom, it mag/ concern.-

Be it known that we, CARL HOOHSTADT, PHILIPP WENZEL, and HERMAN HEINEBACH, of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Imp'rovementsinMoldsforOastingType,of which the following is a full, clear, and exact de scription, that will enable others to make and use the same, reference being had to the acro companying drawings, forming a part of this specification.

The object of this improvement is to provide means for breaking off the jets' from the body of the type before the same are discharged from the molds, the jets beingthrown into one receptacle and the type into another, thus entirely obviating the necessity of doing this work by hand. I

Figure 1 .is a front view of the jaws in which the opposite or back side; Fig. 3, a side elevation showing parts omitted in Figs. 1 and 2. Figs. 4, 5, 6, 7, and 8 are different sectional views of the mold-blocks, and Figs. 9 and 10 are views of the type and jet.

Most of the mechanism is necessarily shown in the drawings, in order to fully bring out the improvement. The description willtherefore be confined to the improved features and the parts to which they are attached.

Referring to the drawings, A A represent the jaws to which the mold-blocks B B are secured, Fig. 2 having parts broken away, showing the manner of rigidly securing the moldblocks, whichfeature is common to this'class of machines. The upper jaw, A,to which the upper half, B, of the mold is attached, opens upward on a pivot to the position indicated by the dotted lines in Fig. 2, while the under 4o jaw, carrying the lower half, B,of the mold,

remains in a stationary position, the upper jaw being raised at the proper time toa'llow the type and jet to drop out of the molds.

The molds and parts to which they are attached being set at about the angle indicated in Figs. 1 and 2, the type naturally drops out of the molds when the jaws separate, and gravitates into the receptacle provided to receive it.

Fig. 4 is a vertical central longitudinal section of the mold-blocks, showing the back side the mold-blocks are placed; Fig.2, a view of .described by the jet-ejecting arm.

of. the mold-chamber a, Fig. 5showing the op posite side of the same.

Fig. 6. shows the type-body a and the jet a in position as they are cast in the molds, the

projects a little way into the chamber of .themold, so that in the process of casting thetype the surplus metal forming thejet will beheld in place and broken off from the foot of the type-body when the upper mold block is raised to discharge the type.

Fig. .8 is a vertical 'longltudinal section in the plane 8 8 Fig. 5, showing the pin b recessed in the upper half of the mold, the outer end just projecting into the chamber a, in order to have sufficient hold of the type to raise it out of the mold, when it drops onto the slide D and is carried away. The projecting end of this pin 1) is placed so as to have contact with the type near 'thefoot and at the junction with the jet. A companion pin, b, is placed in the upper half of the mold, and has a bearing near the face end of the type. When the upper half of the mold rises up, these pins break or separate the type from the jet, the type dropping out as the mold opens, the jet being temporarily retained in the lower member of the mold by the pin b, (or its equivalent means,) and is dislodged or ejected therefrom by means of the curved arm D coming in contact with that portion of the jet projecting from the mold, the jet dropping into the funnelshaped receptacle .d, (sce Fig. 3,) and is entirely separated from the type.

The curved arm D is adjustably secured to the upper half or member of the mold and receives the required motion therefrom, the dotted lines indicating the opposite position of the jet-ejecting arm when the mold is wide open. The end of the ejecting-arm having contact with the jet is beveled, as shown at d, Fig. 2, whereby the jet is wedged away from the mold in a direction different from that of the curve In this case the jet-ejecting arm is attached to the upper member of the-mold; but it isobvious that the arm may be connected to any part of the mold or machine whereby the required motion is imparted to the same,and the jet automatically ejected after being broken from the type. The ejecting-arm is adapted to move in close proximity past the jet end of the mold and eject the jet when the mold is open.

Figs. 9 and 10 show opposite sides of the type-body and jet broken apart, the bearinginarks of the pins being indicated. By this arrangement the type and jet are automatically" broken apart by the opening of the mold, and automatically discharged into receptacles entirely separate from each other, thus saving much valuable time and labor in the process of casting type. 7

Having thus described our invention, what we claim as new, and desire to secure by Let ters Patent, is I 1. In a type-casting machine, the combination, with the lower stationary member of the mold, having a detaining device in the jetcasting portion, of the. upper mold-section, provided with similar detaining devices in the type-casting portion, substantially as described.

2. In a type-casting machine, the combination, with the lower or stationary half of the mold B, of the pin I), the upper movable half of the mold B, and the pins 1) 6", whereby the jet is broken from the type in the process of casting, substantially as described.

3. In a type-casting machine, the combination, with the type-mold, the upper member of which is provided with a type-detainer, and the lower member of which is provided with a j et-retainer, of a jet-discharging arm connected with a moving part of the machine and moving in close proximity with the jet end of the mold, substantially as described.

. 4. In combination, substantially as set forth, the mold having in one member atype-da tainer, and in the other or companion member a jet-detainer, and a jetejecting arm moving past the jet end of the mold while the mold is open, whereby the type and jet are automatically broken apart when the mold opens, and the jet ejected therefrom.

5. In combination, substantially as set forth, the mold having a jet-detainer in one member, and a jet-discharging arm on the other member, provided with a beveled end engaging the projecting portion of thejet to Wedge it oft from the mold. and eject it therefrom when the mold opens.

6. In a type-casting machine, thecombination of the mold and a jetdischarging arm at taehed to and receiving motion from a moving part of said machine, substantially as described.

7. In a type-casting machine, the combination, with the upper and lower parts forming the mold, of the pins b b b and the curved arm D, adjustably secured in relation to said mold and adapted to move therewith, substantiall y as and for the purpose set forth.
